First of all you do not appear to be running an Anti-virus program.
Have you followed any of the instructions in PP's thread other than moving HiJackThis and running Ewido?
Go into Add/Remove and look for and remove the following if listed;

winupdates
Viewpoint
Napster

Now go into each of these programs and check Preferences and disable them from running at Start up;
Nero
Direct CD
My Space
Yahoo Pager
a-squared
Ewido.
Next go into the link I gave you before. Download all the programs PP tells you to download, install them, update them but don't run them yet.



Please go back to PP's thread and run at least three of the online scans. Have the scans remove everything found.
Then follow his instructions for booting to Safe Mode and run all the programs you downloaded from his link, beginning with CCleaner.
Run FULL SYSTEM scans with all the other programs, including again Ewido and also a-squared and have all of them fix whatever is found. Save the logs for all of them someplace where you can easily find them.
Reboot to Normal Mode. Run a new HJT scan and post that new log along with all the other logs I asked you to save.
